Coda-final consonant deletion has been extensively documented in Eastern Andalusian Spanish; however, its effects on neighbouring segments is still unknown. Scholars working on consonant deletion in Eastern Andalusian Spanish have mainly focused on /s/, given the semantic importance of this consonant in Spanish. As a result, other consonants which are often deleted syllable-finally in this geolect have been studied to a much lesser degree. The present paper aims to expand the traditional view on vowel doubling by analysing /-s/, /-r/ and /-Ɵ/ deletion before /a/. Firstly, the speech of 24 speakers from El Ejido (Eastern Andalusia) is analysed to ascertain how the deletion of word final /s/, /r/, and /Ɵ/ changes the quality of a preceding /a/. Secondly, a perception test is carried out with native speakers from the local area to confirm whether these speakers can differentiate perceptually between word-final /a/ and /a/ preceding underlying /-s/, /-r/, or /-Ɵ/. This paper presents two main conclusions: 1) /-s/, /-r/, and /-Ɵ/ deletion changes the quality of a preceding /a/ to different degrees; 2) EAS speakers can identify whether /a/ is followed or not by an underlying /-s/, /-r/, or /-Ɵ/, but they cannot identify which consonant has been deleted in each case.
